Mountain-to-Sea Resource Management
Bringing multiple values to the table in local decision making – NSF Coastal SEES
By Leah Bremer “Want to carry one up?” the natural resource management team with Limahuli gardens in Haʻēna, Kauaʻi asks us as they hand out potted endangered plant seedlings before our hike up the trail toward one of their native forest restoration areas. We arrive 30 minutes later to the first restoration plot and are […]
Read MoreJoint Management of an Interconnected Coastal Aquifer and Invasive Tree
Kiawe (Prosopis pallida), a mesquite tree considered invasive in many parts of the world including Hawai‘i, has been shown to reduce regional groundwater levels via deep taproots. In areas where aquifers are primary sources of fresh water, kiawe control has the potential to be an integral component of water management planning. We develop an analytical […]
Read MoreInforming Water Policy in Hawaii with Transformative Interdisciplinary Research: UHERO’s Role in ʻIke Wai
By Kimberly Burnett and Christopher Wada UHERO’s Project Environment will be leading the economic analysis for a new National Science Foundation project addressing critical gaps in the understanding of Hawaii’s fresh water supply that limit decision making, planning and crisis responses. ‘Ike Wai (from the Hawaiian ‘ike, (knowledge), and wai, (water) spans geophysics, microbiology, cyberinfrastructure, […]
Read MorePayments for Watershed Services as Adaptation to Climate Change: Upstream Conservation and Downstream Aquifer Management
Economically optimal groundwater extraction allocates water over space and time to its highest and best social use. But optimal management of water resources also requires optimal investment in watershed capital, even as the climate is changing. We augment a standard coastal groundwater management model with stock-dependent extraction costs to include recharge-enhancing natural and produced capital […]
Read MoreUnderstanding the Links Between Local Ecological Knowledge, Ecosystem Services, and Resilience
By Kim Burnett and Cheryl Geslani UHERO’s Project Environment has received funding from the National Science Foundation to participate in an interdisciplinary, international project that spans the natural and social sciences as well as the terrestrial and marine spheres. UHERO is partnering with scientists, resource managers, cultural practitioners and private landowners in Hawaii and Fiji. […]
Read MoreHow Do We Manage Our Interdependent Environmental Resources?
By Christopher Wada Managing water resources requires an understanding of the linkages between key hydrologic factors and direct human influences. The problem is further complicated by the fact that water resources are often interdependent, which suggests that management should also account for ecological interlinkages. For example, a forested upstream watershed may replenish an underlying groundwater […]
Read MoreIncentivizing interdependent resource management: watersheds, groundwater, and coastal ecology
Managing water resources independently may result in substantial economic losses when those resources are interdependent with each other and with other environmental resources. We first develop general principles for using resources with spillovers, including corrective taxes (subsidies) for incentivizing private resource users. We then analyze specific cases of managing water resources, in particular the interaction […]
Read MoreOptimal Joint Management of Interdependent Resources: Groundwater vs. Kiawe (Prosopis pallida)
Local and global changes continue to influence interactions between groundwater and terrestrial ecosystems. Changes in precipitation, surface water, and land cover can affect the water balance of a given watershed, and thus affect both the quantity and quality of freshwater entering the ground. Groundwater management frameworks often abstract from such interactions. However, in some cases, […]
Read MoreOptimal groundwater management when recharge is declining: a method for valuing the recharge benefits of watershed conservation
Demand for water will continue to increase as per capita income rises and the population grows, and climate change can exacerbate the problem through changes in precipitation patterns and quantities, evapotranspiration, and land cover—all of which directly or indirectly affect the amount of water that ultimately infiltrates back into groundwater aquifers. We develop a dynamic […]
